Materials for, and methods of, colorizing a metallic surface with micro-gratings using vibration cutting technologies are provided. Micro-gratings on aluminum, brass, and stainless steel surfaces can be rapidly created to effect, under illumination, at least one color observable in the visible spectrum using elliptical vibration texturing, a vibration-assisted mechanical cutting process. The modified metallic surface can display multiple visible colors, an iridescent effect caused by changes in one or more cutting parameters employed to produce the micro-gratings, the angle of illumination by an incident light, and/or the viewing angle of the surface under illumination.

In some embodiments, a method may include selectively applying a mask to a first surface of a substrate. The mask may include one or more components defining a selected pattern and having a non-uniform density. The method may further include etching the first surface of the substrate based on the mask and selectively processing the first surface of the substrate to produce a multi-dimensional artwork.

A method for memorializing a sports jersey via creating a shimmering light-reflective pattern resembling a three-dimensional wave on a plurality of two-dimensional metallic surfaces features obtaining a plurality of planar metallic blanks. The method features obtaining an angle grinder having a circular grinding disc located thereon. The method features embedding a first series of arc-shaped striations sequentially located one above another along a first striation axis on each metallic blank via operation of the angle grinder. The method features embedding subsequent series' of arc-shaped striations sequentially located one above another along subsequent striation axes on each metallic blank via operation of the angle grinder. This step is repeated until the desired shimmering light-reflective pattern resembling a three-dimensional wave on a two-dimensional metallic surface is achieved. The method features assembling the metallic blanks, one atop of another creating layers.

Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a first pattern defined by a first particulate mineral mix and a second pattern defined by a second particulate mineral mix different from the first particulate mineral mix. Locations of the first pattern have a first average thickness perpendicular to the slab width and the slab length, and locations of the second pattern have a second average thickness perpendicular to the slab width and the slab length that is different from the first average thickness.

A processing method for a surface of a workpiece using a rotating cutting tool, includes a processing method for forming a cut pattern by rotationally cutting a surface of a workpiece using a rotating cutting tool having cutting edges extending in a rotation axis direction at a plurality of circumferentially separated positions on an outer circumference of a body thereof. Each of the cutting edges includes a plurality of segmental edges segmented at an equal pitch in the rotation axis direction. A ratio of depth d to width W (d/W) of a knife mark formed on the surface of the workpiece by the segmental edges is not less than 3/100.

Platform movement systems and methods of using the same. A system for moving a platform of the present disclosure can include a first actuator pivotally attached to a base, the first actuator having a first rod positioned therethrough and configured to move the first rod in a first direction and an opposing second direction along a first rod axis; a second actuator pivotally attached to the base, the second actuator having a second rod positioned therethrough and configured to move the second rod in a first direction and an opposing second direction along a second rod axis; an arm attached to the base using an arm connector; and a platform coupled to the first rod, the second rod, and the arm, the platform configured to move about the base upon operation of the first actuator and/or the second actuator.

An outdoor marking product comprising a chlorophyll-based agent for highlighting living greenery. The chlorophyll-based agent can be non-detrimental to the health of the living greenery. When viewed by a viewer at a minimum predefined viewing distance, the living greenery treated with the chlorophyll-based agent can be visibly distinguishable from and shinier than neighboring untreated living greenery. When the viewer is nearer than the minimum predefined viewing distance, the difference in shine and color between the treated living greenery and the untreated living greenery can be substantially unnoticeable.

An improved advertising system can include a location having a substantially large expanse of living greenery, a predetermined design for an advertisement, and a chlorophyll-based agent. The location can be observable by viewers at a predefined minimum viewing distance. The chlorophyll-based agent can be used to paint the predetermined design on the living greenery. The chlorophyll-based agent can be non-detrimental to the health of the living greenery. The predetermined design painted on the living greenery with the chlorophyll-based agent can be only viewable by viewers at the predefined minimum viewing distance. Living greenery treated with the chlorophyll-based agent can be visibly distinguishable from and shinier than neighboring untreated living greenery. When a viewer is nearer than the minimum predefined viewing distance, a difference in shine and color between the treated living greenery and the untreated living greenery can be substantially unnoticeable.

A process for producing an identifiable hand tool includes a machining step which uses machining tools to produce a rough part of the hand tool; a setting identification step which forms a identification area with an identification groove on the surface of the rough part; a heat treatment step which proceeds a heat treatment to the rough part; a vibration step which vibrates the rough part; a surface treatment step which electroplates the rough part to form an electroplating layer on the surface of the rough part to form a hand tool with a base color identification layer, and a coloring step which uses a Charged Coupled Device to determine a depth of the identification groove and uses a coloring pen of a coloring machine to perform coloring processing to form an identification portion with a different color from the base color identification layer.
